  • the so formed sideways Ball valve flowing towards the axis of rotation has a comparison a more ideal solution for the ball valves flowing from below Mixing characteristic. This can be due to favorable deflection effects by the inclination of the baffle on the throttle body in returned to the areas between 60 ° and 120 ° ball rotation become. Due to the favorable characteristics and flow conditions the three-way valve is suitable for cooling circuits with electrically operated pumps. These can be smaller be dimensioned so that their power consumption is reduced and the overall efficiency improves.
